Application April 6,

To all whom it concern:

Be it known: that I, WILLARD S. TUTTLE, of Brooklyn, in-the'county of Kings, in the State-offNew York, have invented new and useful-Improvements in Hot-Air Registers,

ef-whfich the following, taken in connection with the]accompanying drawings, isla full, e1ear,' and exact description.

This invent on: relates to certain improvements in hot ailregisters of the slide-valve type, a'ndis' especially adapted foruse in l comparatively thin side walls, or in the floors of a building. I

- One of-the essential objects of this inven .tion' is to. produce a comparatively light shallowregister with as few parts as possible i by making the boxof less depth than the width of any one of the other damperblades and arranginglsaid blades wholly within the box close to t walls without .ob'structin the hot air' flue's,

and at the same time to a 0rd comparatively large 0 enin s by arelatively small moveform and quick Y j in the following description.

In the draw1n'gs-F1gures respectively, to

the various features of my "invention. Figs.

45,, 5,"6 and 7 are enlarged sectional views I taken respectively on lines 1-4, '5.-5, 6 -6,

, and 7-7, Fig. 1.;Fig. '8 is a further enlarged longitudinal sectional view through 1).

.a portion .of one end of the frame, and adjac'ent portions of the slide valves. Figs. 9,

10 l and ll'are perspective views respectively of the outer and inner valves and the box frame for receiving and supporting the same,

I This hot-air register comprises essentially a grille-plate 1'-; a comparatively shallow box-frame 2- and a plurality of slide ,"v'alves 4 all of which parts jvare preferably rmed ofsheetmetal so as to lighten the unitary structure, and thereby c'heapen the cost of transportation.

The central portion of the plate I,

I substantially equal to the area of the framebox -2-, is grilled or perforated, leaving Bpecijlcation of Letters Patent.

imperforate substantially flat margin projecting some distance beyond the perimeter of the frame and ada ted to abut against the face of the wall or ing through which the frame is inserted.

' Theinner edge of the margin of the grilleplate is provided with ascries of inturned grille plate and which is fitted within; and

connectin with said'grille-plate. v The box-frame -2 is preferably made of a sin le piece of sheet-metal havin its sides an ends bent outwardly and tted around the marginal flange 7- and its bottom depressed outwardly a" slight disand ends, a marginal groove .9- which is co-extensive with the length of said sides and ends.

Portions of the bottom of the frame .-2

and intervening spaces which are substanfaces of theflange j1l' and projecting inwardly therefrom for receiving suitable fas-' tening means, as screws 13, which are passed through apertures in the lugs -8 and engage with threaded apertures in the inwardly, projecting ends of the braces 1'2'- so as to impinge the marginal flange 11-, between the lugs 8 and braces 12,,;;t hereby firmly securing the frame 2- to the grille-plate.

Portions of the flange -7 are cut away to allow the entrancefof the braces into close proximity to the ears or lugs 8 although the inner edges of the marginal flange 11'- oor around the open retains the. vbox frame -'-2- in' operative tance, forming at its junction with the sides tiallyiequal to twice the width of the barsupper portions abutting against the inner lugs or cars --5 to which is secured 'by rivets -6,. a marginal flange '7-- 1 ,ing against the back face ofthe margin-o the are cut away at intervals forming a series of separated parallel transverse bars --10-' "ofthe-frame and grille plate, one upon the other, thereby relieving in a measure the 5 strain upon the bolts or screws -13.

One of the transverse bars 10- of the,

bottom of the frame .2 is united directly to one of the ends of theframe and has its opposite longitudinal edge bent downwardly forming a reinforcing flange l4. The remaining'bars- 1Q are united at their ends to the sides of the frame "-2- and have their front and rear edges bent in opposite dircctio'ns; forming reinforcing flanges 14- andfl5.. y

The front, edges of the bars 10- to which the flanges 14 are united are [pressed upwardly a slight distance, forming lengthwise beads 16, whichare disposed in, a'plane slightly'above the remaining portionsof the bars, and serve as hearing faces upon whiclrthedaniper 3- slides so as ,not to marfjor disfigure the exposed outersi irface the bars 1O.

The slide'valves ,3- and -4 are each jformed' of sheet metal of substantially the same ,width; as the: inner width of the frame 2, "but .are' shorter than the interior lengthpof the frame'a distance substantially equaljt o the width *of one of the openings between the bars 10 so as to allow for a limited lengthwise movement of the slidevalves in saidframe.

The innersides' of the grooves -9- are deflected oroi'lset inwardly a slight distance to form a guide and bearing for the inner valve 3; and theopposite longitudinal Hedges off the valve 3' are oflf-set or de fiected outwardly, forming flanges 1-17-- which enter andride 1n the lengthwise grooves -9'1n 'the oposite' s des of the frame 2-..' This slide-valve 3 is substantially flat and provided with a series of,

in this instance, four transverse bars 18- which are spaced apart forming intervening spaces v20 "of substantially -the same width as the spaces between the bars -10+,

while the bars 18 are of substantially the same 'width as the bars 10 In like tially flat and rests upon the outer face of the valve 3- and is provided with a series of parallel bars 21 and intervening spaces j22j, the, bars 21 being of substantially-the same width as the bars frame f2%' respectively, while the spaces a 22+e areof substantially the same width "as 'thej s aces between the bars 10 and are," therefore, equal 'in areafto the spaces The front and rear edges of the and thelongitudinal edges o: the damper strains.

' -53 upon the bars -1 manner the sliding .valve -4tis substanare also bent upwardly forming '.addi

tioual lengthwise flanges --2f5 It is evident from the foregoing descrip-' 'tion, and the accompanying drawing, that I each sliding damper 01' valve is provided with a series of, in this instance four, substantially parallel bars united at-the ends,

and forming a series of, in this instance, three'intervening spaces and that the flanges at the edges of the side pieces and cross-bars of each valve serves to stiffen and strengthen of the valve 3+- are also pressed outwardly-a slight. distance above the plane of the r'enain'ing portions of the bars forming beads or lengthwise bearings -26- for the-outer slide valve 4 to prevent marring of the exposed surfaces of the outer faces of the bill's I I The upturned-flanges '.l5- on the rear edges of the bars 10 form abutments or limiting stops for limitingtheopening movement of the'slide valve 3 and the inwardly turned flanges, as -23--', of the slide valve 3- perform similar function'by engaging the front edges of the bars -10 to additionally limit the, open sliding movement of the valve -3 In like manner the front and rear flanges 23 and 2 l-'ofv the slide valve 4 form suitable abutments for en gaging respectively the front andrearedges the same against compression or torsional The front edges of the bars 18 of the bars -l8 .of the valve :3.Ifor

limiting the movement of the valve relatively to the valve 3, and also for affording means for operating said valve The slide valve 4 is provided with an- I operating member 30.projecting through an elongated slot in the grille-plate -1 and provided with a spring frictiondisk -31 which is seated upon a shoulder 32 and frictionally engages the inner face ofthe grille-plate 1' to hold the sliding dampers or valves '3 and +4- in their adjusted position. I In order that the innerslide valve- 3 may be forced to its closed position by the closing of the valve 4-, I provide onetend of the valve '3- with a forwardly projecting arm 34 of substantially the same length-as the width of the bar to which it is attached andterminating in an out-turned shoulder or abutment-35 The inner portions of-the flange 7 are depressed inwardly from the grille-plate a suflicient distance to form an interposed groove: or space. 36+ for receiving the reduced ends of a series of transverse rein-' forcing bars -37 which are usually made of steel; and bear against the inner face of the sheet-metalgrille-plate to support the, same against inward depression, the reduced ends of said bars being best shown in F 6,-

as seated in the groove 36 Assuming tially half of said] space and b moving be moved in a similardirection-ind now.,that the valves and are closed, as seen in Figsq3 and 45, in which .fpositiqriitm bars '18- and 21 cover the the corresponding abutments-23'-g and +24% of the valve 4-, whereupon the continued movement of the valve -3. by the operating, member causes the ,abutments -'23' and '24- of the valve to-engagevand slide the'valve 3 to the limit of its movement, orv across the bars lie one over the other, thereby registering the openings between said bars with each other.- On theother hand, whenit is desired to'elose 'the valves, the operating member 30-.- is.

. ment andmoves the va moved in the opposite direction, thereby sliding the ,valve t in the same direction until the front bar -21- engages the abutlve 3-- to the limit of its movement.

The grille-plate '1- and frame 2 are secured together, by the screws 13 and the flanges 7- projectinwardly in close proximity to the outer face. of the slide valve -3 suflicient toprevent undue displace ment of the valves from the seats of the frame -2- upon which they slide,bu tithese I valves are further held against displacement v by the friction-disk 31 having sliding frictional engagement with the undersideof the grille-plate, the-pressure of said spring being sufficient to retain the slide valves in operative position relatively to each other.

It is nowifevident that by removing; the

screws 131- the grille-plate with its flange 7 may'bereadily removed, after'which withdrawn 7 through the open .side of the 5 frame 2 thus affording a simple and comparatively inexpensive means for assembling the gpa' rts of the register,'and materially reducing the' cost of manufacture. l ,W'hat I clTaimz' 1.
